    Question

    What is the discriminant value of the equation x to the power of 2 end exponent plus 3 x plus 5 equals 0 ?

    1. -11    
    2. 1    
    3. 2    
    4. Either 1 or 2.    0

    hintHint:

    Any equation of the form p (x) = 0, where p (x) is a polynomial of degree 2, is a quadratic equation

    The correct answer is: -11

      Step 1 of 1:
      We have given an equation x to the power of 2 end exponent plus 3 x plus 5 equals 0
      Now,
      b to the power of 2 end exponent minus 4 a c equals 3 to the power of 2 end exponent minus 4 blank cross times blank 1 blank cross times blank 5
      equals negative 11 less than 0
      The discriminant value is less than zero, so it has no real solution.

      The discriminant is the part of the quadratic formula found within the square root.
